I have used sysmpu example for investigate how MPU detect acceses to protected area.
I can see BusFault handler code is detect exact address, access to what cause fault and from what slave it arrive.
But if access issued for peripheral area (0x40000000 - 0xFFFFFFFF), BusFault is occurs but code is show that no any slave errors at all.
How to detect exact fault address in case when wrong access is issued to peripheral area ?
MPU in K82 covers real memory and partially ( or all ?) peripheral area but ecat address are not decoded.
By the way could you recommend some guide/app note where explained how-to detect information from major ARM fault exeptions ?
